Were the 50's originally 6 or 12 volt? My '53 50 had two new 6volt batteries installed when I got it. They were installed in series (12 volt). The coil is also 12 volt. This probably seems like a dumb question, but I guess I 'thought' 50's were 6 volt? If not, that's better anyway, just wanted to check to be sure! Judging by the jumper cable between the batteries, it looks like it was meant to be this way as one terminals has a smaller hole in it than the other. Also, still has the original style generator on it. Just got all my lights fixed and ready to go and didn't want to risk buring up my bulbs if this was wrong and should be 6volt? Thanks in advance!

Guy, the 50 was built 12 volt.

Clooney is correct again, as usual. Why they used two 6 volt batteries, is however beyond me! Got an answer for that one, Clooney?

Ray, I'm not sure I have the correct answer but I have an educated guess. When the 12 volt electrical systems started to come into use there was no such thing as a 12 volt "heavy duty" tractor battery with high cold cranking amps. Car type batteries wouldn't hold up long with their light duty plate isolators & non-rubber cases. But there were plenty of heavy duty, rubber cased 6 volt batteries with solid plate isolators & leak-proof caps that had an amp hour rating of 85 each (115 each on the 70) & the added weight wasn't a problem on a tractor so that's probably the why they went with 2-6 volters. Now keep in mind this isn't fact it is just my opinion.

Clooney is right ,the 70 amp 12volt car batteries just didn't have enough in cold weather. The 2- 6 volt batteries produced 230 amps and would last quite awhile cranking. The 70 amp car battery produced 210 amps ( 70 times 3 ) for just a short period. Its like taking your garden hose and a funnel ,pour 3 gal of water in the funnel ,now take 2-5gal. buckets and pour that in,you get a lot more flow and last longer doesn't it.Today you can buy a 12 volt battery with more power than the 2 -6 volt batterys and get along ok,but it's not original, cost about the same.
